I can't believe this is the last post for 2012. So, an explanation of this puzzle is in order. As someone pointed out, you may have thought there was an audio problem since you couldn't hear anything. Sorry, that was actually the hint - it was silent. That was to differentiate it from the other Christmas song "O Holy Night". The correct answer for this puzzle is "Silent Night, Holy Night". Certainly wasn't the least punniest puzzle I've ever done.
That's more than just a wish this time of year, it's the solution to last week's puzzle. Congratulations to Jenni from Madison for getting the answer right, although I do like the answer that Evelyne V from France gave: "Variety is the spice of life." I may have to work that in to a future WIR.
They both were supposed to say the same thing. Which one did you like better? By the way if you didn't get this one, I'll give you a hint: I'm guessing it might be under some Christmas trees this year.
As I said in the hint, you need to know a little chemistry. But since no one got the correct solution, I'll leave it open to discussion.
